Aston Villa could be plunged into a goalkeeping crisis for Saturday evening's home Premiership clash with Bolton after Stuart Taylor suffered a knee injury in the 2-2 draw at Sheffield United.
And it could mean a first team debut for Austria Under-21 keeper Robert Olejnik against Sam Allardyce's side.
Taylor was limping badly during the closing stages at Bramall Lane after a fine performance and the former Arsenal player was unable to take goal-kicks.
He is currently deputising for Villa number one Thomas Sorensen who is sidelined with the knee injury sustained in a challenge with Middlesbrough defender Emanuel Pogatetz two and a half weeks ago.
Martin O'Neill confirmed: 'Stuart made some great saves but he picked up a knee injury. He was examined by the physios and doctors after the game. Hopefully we'll have more news soon.'
Olejnik, 20, was signed by O'Neill's successor David O'Leary in 2003 as a possible long-term replacement for Sorensen from FK Austria Wien and signed professional forms 12 months later.
Olejnik - nicknamed 'The Beast' because of his bulky frame - has been on the substitutes' bench for the last three games with Manchester City, Portsmouth and the Blades.
The player has represented Austria at under-17 and under-19 level and made his under-21 debut for his country this season.
But it would be a demanding test if he has to face the physical challenge provided by Bolton.
Villa's only other goalkeepers are 18-year-olds Lee Boyle and Stephen Henderson.
Defender Wilfred Bouma is also battling to be fit after suffering a head injury which required several stitches against Neil Warnock's side.
